Keil C does not support

Jim King over 19 years ago

Keil C does not support this line:

typedef const UINT32 volatile xdata *PCVX32;

it just support this way

typedef const volatile UINT32 xdata *PCVX32;

but other ANSI C compilers support both.
Is it a bug or something else?

The position of "volatile" is the aim.You can try

typedef const long volatile *PVLONG;
and

typedef const volatile long *PVLONG;
on Keil C and VC.
It is strange that it can both be compiled successfully on Keil C if I change the type "long" to "int".

And if there is no "const", it's also OK.
